If there is no ISP, then you have to make do.  Just for example, I have
made a semi-arbitrary choice of fec0::/64 for our ad hoc net.  I say it
is semi-arbitrary because fec0::/64 used to be assigned to "site-local"
addresses by IETF.  Site-local addresses went away, but I think the
MANET working group has tried to revive them for ad hoc networks.

You are eliding a lot of different ideas, here.

I think that everybody who wants an "IP numbers for all" and an Internet
unfettered by NAT, also wants IPv6 numbers.  This includes most CWNs.
But I cannot specifically tell you how the groups at the Summit would
use IPv6.  That would be a good question for the cwn-summit mailing list.
